Variables in >D section cannot be set via MQTT/Console

[DennisXK]

Hi everyone, I am experiencing an issue where script variables cannot be updated externally on an ESP32-C3 running Tasmota 14.4.1 (compiled via TasmoCompiler).

My Setup:
I am using a Tasmota script to control two fans via PWM.

Section >D: Variables FanSpeed1 and FanSpeed2 are defined here.

Section >S: PWM calculation and logic are handled here.

Section >W: Sliders are defined and work perfectly within the Web UI.

Section >J: Variables are correctly published as JSON in the SENSOR message.

The Problem:
I am unable to update these variables via the Console or MQTT. Every attempt to address the variable directly or via standard commands results in Command: Unknown.

Tested Commands (all failed):

FanSpeed1 50 -> Command: Unknown
=>FanSpeed1 50 -> Command: Unknown

event FanSpeed1=50 -> Command: Unknown (and EVENT is not recognized as a command)
script FanSpeed1=50 -> Command: Unknown
Var1 50 -> var1 not found
v1 50 -> Command: Unknown

Observations:
While the variables work internally (Web UI sliders change the fan speed immediately), the command parser seems unable to link incoming MQTT/Console strings to the script variables. Even using Backlog does not bypass the "Unknown Command" error.

The documentation suggests that you have to use the Script command to get/set variables from outside of scripter code.
